Hmm. --verbose please. While this clearly doesn't do what you intended I think it should not have crashed qemu. pvUSB devices should work on emulated controller (and emulated devices should work on the pvUSB controller). If they don't you probably taking shortcuts somewhere which work only for the pvUSB device on pvUSB controller case. Please check. cheers, Gerd From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gerd Hoffmann Subject: Re: [PATCH 0/2] Xen pvUSB correction Date: Tue, 27 Sep 2016 10:51:19 +0200 Message-ID: <1474966279.26376.5.camel@redhat.com> References: <1474893837-13010-1-git-send-email-jgross@suse.com> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Return-path: In-Reply-To: <1474893837-13010-1-git-send-email-jgross@suse.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+gceq-qemu-devel=gmane.org@nongnu.org Sender: "Qemu-devel" To: Juergen Gross Cc: anthony.perard@citrix.com, xen-devel@lists.xensource.com, sstabellini@kernel.org, qemu-devel@nongnu.org List-Id: xen-devel@lists.xenproject.org On Mo, 2016-09-26 at 14:43 +0200, Juergen Gross wrote: > Trying to use pvUSB in a Xen guest with a qemu emulated USB controller > will crash qemu as it tries to attach a pvUSB device to the emulated > controller.
